HOC simulations of miscible viscous fingering of a finite slice: A new insight
Mijanur Rahaman, Jiten C. Kalita, Satyajit Pramanik
We investigate the dynamics of viscous fingering (VF) in miscible slices in homogeneous, isotropic porous media. The fluid flow is governed by incompressible Darcy's law, whereas t…

Towards enhanced mixing of a high viscous miscible blob in porous media
Mijanur Rahaman, Jiten C. Kalita, Satyajit Pramanik
In this study, we investigate the rectilinear displacement and deformation of a highly viscous, miscible circular blob influenced by a less viscous fluid within a homogeneous porou…

Dissolution-driven transport in a rotating horizontal cylinder
Subhankar Nandi, Jiten C. Kalita, Sanyasiraju VSS Yedida +1
We study the combined effects of natural convection and rotation on the dissolution of a solute in a solvent-filled circular cylinder. The density of the fluid increases with the i…
